🧐[问题] DragSortTable可以部分拖拽排序吗

DragSortTable可以部分拖拽排序吗？比如说表格里面的前两行是固定的顺序，后面几行才可以拖动排序这样的

Start by locating the DragSortTable entry point and reviewing its current drag-sorting behavior and examples. Clarify how fixed leading rows should be configured and what should happen when dragging reaches them. Done means the first two rows retain their order while subsequent rows can be reordered, with documented behavior and coverage for that case.
